adding greedy space to model url splitter

I am migrating a JMVC app over to CanJS and encountered strange DOM Exception 12 errors on model CRUD events.  It took me a while to chase them down and discovered that the splitter employed in CanJS was failing to properly spit on my URLs because I used multiple spaces because I like all my routes to line up "just so" for better readability:

```javascript
        findAll:  "GET    /api/" + AWT.api_version + "/advertisements.json",
        findOne : "GET    /api/" + AWT.api_version + "/advertisements/{id}.json",
        create :  "POST   /api/" + AWT.api_version + "/advertisements/advertisement.json",
        update :  "PUT    /api/" + AWT.api_version + "/advertisements/{id}.json",
        destroy : "DELETE /api/" + AWT.api_version + "/advertisements/{id}.json",
```

JMVC handled these routes okay.  

This little fix just makes the splitter greedier to handle the extra spaces.
